ENVIBLOP.

Application filed January 25, 1917. Serial N 0. 144,462.

To all whom it may concern:

Be it known that I, YOSHITADA YOSHINO, a subject of the Emperor ofJapan, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented certain new and useful Improvements inEnvelops, of which the following is a specification.

This invention relates to envelops, and more especially to a new andnovel construction thereof, whereby a more sanitary cover or inclosurefor letters and parcels is secured.

The objects of the invention are, to provide an envelop of pleasing andartistic design, to provide an envelop in which the blank form may beout with as'little waste of paper material as may be possible, toprovide an envelop requiring a minimum amount of gummed surface inconstruction, to improve the means of sealing so that tampering with theenvelop may be readily detected, and to construct the blank from whichthe envelop is made, so that the glue for securing the flaps in positionmay be applied only on one side thereof.

To this end the invention consists inthe peculiar construction of anenvelop designed to open at the end for insertion of the letter orparcel, and designed with two flaps, one of which is gummed for aportion of its length to seal on one side of the envelop, and the otherflap to fold upon the opposite side and be sealed by afiixing a postagestamp thereto.

The invention further consists in the arrangement, construction, andcombination of parts.

Other objects and advantages will be apparent from the following detaildescription, and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimwithout departing from the spirit of the invention.

In the drawings, Figure 1 is an elevation of the rear side of an envelopto which my invention has been applied. Fig. 2 is an elevation of thefront or address side of the envelop. Fig. 3 is a plane view of theblank before folding to form the envelop. Fig. "I is a perspective ofthe envelop showing the flaps partly open for insertion of a letter orparcel.

Referring to the drawings, the envelop, in the preferred form ofconstruction, consists of the front, or address side 5, from whichextends the end flaps 6, 7 and the inner flap 8, and outer flap 9; saidouter flap 9 having an extension 10, which, when the envelop is sealed,projects into a slot 11, cut in the front side of the envelop.

In constructing the envelop, the blank is first provided with gummedsurfaces 12, 13, 14, the inner flap 8 then being folded upon the part 5,flaps 6, 7 then being folded in upon flap 8, and flap 7 being glued toflap 8. Flap 9 is then folded upon flaps 7, 8 and glued thereto.

The envelop thus formed, is then in commercial form, and ready forinsertion of the letter or parcel. To close and seal the envelop, theend flap 6 is inserted beneath the outer flap 9, and, if desired, pastedto flap 8, although this is not necessary. The ungummed portion 15, offlap 6, is cut and formed to facilitate insertion beneath the outerflap. The extension 10 is then inserted in slot 11, located in the upperright corner of the envelop, and a postage stamp affixed thereto,completes the sealing of the envelop. The dotted lines in Fig. 2,indicate the sealed position of the postage stamp. The extension 10, isprovided with perforations 16, to facilitate opening the envelop afterthe postage stamp has been affixed thereto. The envelop shown in Fig. 1is constructed without such perforations.

It will be noted that the construction and manner of sealing the envelopas herein described, is such as to make practically impossible theremoval of contents without detection. Its simplicity will commend theuse of the envelop for business and. private correspondence. The envelopis efficiently sealed by afiixing the postage stamp thereto. The envelopis more sanitary than those of prior construction, as only the gummedsurface of the stamp need be moistened. To,

open the envelop after sealing, -the postage stamp or the extension flapto which it is glued, must be mutilated, and it cannot again be sealedafter cancellation of the stamp, without detection.

WVhat is claimed is:

An envelop cut from a substantially rectangular blank, comprising afront part, an inner flap, folded upon said front part, an end flapfolding upon and glued to said inner fiap, an outer flap folding uponthe inner flap and glued thereto for a portion of its length, an endflap to be inserted beneath Specification of Letters Patent.
